Function

General

This section presents a general overview of the functions of the machine. Most functions are then presented in detailed in separate chapters later on in this service manual.

The machine is freely suspended, which means the outer drum and motor are mounted on a supporting ”cradle” that rests on four shock absorbers for dampening the imbalance in the machine.

The washer drum (inner drum) is belt driven by a motor. This motor is loca-ted at the bottom of the machine and is mounted on the cradle with a belt tensioner. The inner drum is mounted to the outer drum at the rear plate with two bearings sealed against leakage with sealing rings.

The drain valve is a water-controlled diaphragm valve alternatively, an electrical drain valve or drain pump.

The door is of sturdy type that is interlocked with a lock module when in operation.

The control panel contains a program knob for selecting the fixed wash programs and a display.

The program unit is mounted inside the control panel. Contactor, water valves, etc., are located at the back of the machine.

Program unit

The control panel contains a program knob and a display. The panel can also be equipped with two preset buttons.

The control panel and display are used by:

• theusertoselectthemachine’sfixedwashprograms, to select up to two options for each wash program and for information on the wash process and any fault indicators.

• servicepersonnelfornavigationandcontroloftheprogramunit’sserviceprogram.

• programmingpersonnelforsettingandpro-gramadjustmentintheprogramunit’ssoft-ware.

If present, the preset buttons are used for direct start of two preset wash programs.

Using information on torque values from the motor, the weight of each wash is measured before each wash program in order to adapt the amount of water used for washing.

The program unit controls the water valves, drain valve and heating via an I/O board in the rear electrical module. Control signals to external units, such as detergent pumps or external water valves can also be engaged here.

Motor and motor control

The washer drum (inner drum) is belt driven by a frequency controlled motor. The motor is located on a motor shelf under the outer drum and has been arranged with a belt tensioner.

Motor control is microprocessor controlled and can control the acceleration of the drum, its rpm and its retardation very precisely.

Motor control communicates with the program unit through a serial interface.

Door lock

The door lock is electromechanical with twin sa-fety breakers. The lock is bi-stable, i.e. the lock must be given an active signal from the program unit to lock as well as unlock the door.

A separate circuit integrated in the program unit checks and controls the locking and unlocking of the door through a lock module. The circuit has separate controls that the drum is empty and that it is stationary. Through sensors in the lockmodule,thecircuitchecksthedoor’sclo-sed and locked position. Together with other controls the program unit conducts, this will guarantee the door cannot be opened by mis-take.

Detergent compartment

The detergent compartment has four compart-ments for prewash, main wash, rinse and bleaching agent/liquid detergent.

Themachine’sdetergentcompartmentisdescri-bed more thoroughly in the section Detergent compartment.

Drain valve

The valve is a diaphragm valve that is opened and closed through water pressure. The control valve is mounted by the water valves.

Themachine’sdrainvalveisdescribedmorethoroughly in the section Drain valve.

Frame and suspension

The machines are freely suspended, i.e. the drum package can move and is suspended in relation to the frame. In this way, a minimum of vibration passes to the bottom plate, which in turn simplifies installation as a concrete founda-tion is not required.

The machine has four shock absorbers between the bottom plate and the drum package.

Description of fault codes and causes

Fault code 01, NO WATER

This fault code is generated by the programming CPU card.

When filling with water, the level specified by the wash program must be attained within a certain time. This time is normally set to 10 minutes but can vary depending on the type of machine and the software. If the filling time eceeds the maximum allowed filling time, fault code 01 will be dis-played.

Long filling times can be caused by a blocked filler valve, defective filler valve, a break in the cable between the filler valve control board, defective valve control board, leaking level system, etc.

Fault code 02, DOOR OPEN

This fault code is generated by the programming CPU card. The fault code can only arise during an on-going wash program.

This fault code will be displayed if the input for closed door signals that the door has been opened during an on-going wash program.

This can be caused by a bad or defective door lock, loose cable to door lock, problem with door lock edge connection.

Fault code 03, DOOR LOCK FAIL

This fault code is generated by the programming CPU card. The fault code can arise at program start. If the door lock doesn't lock within a certain time after program start, this fault code will be shown.

This fault code will also be displayed if the door lock for closed door sig-nals that the door has been unlocked during an on-going wash program.

This can be caused by a bad or defective door lock, loose cable to door lock, problem with door lock edge connection.

Troubleshooting

26 Troubleshooting

Fault code 04, NTC LOW TEMP

This fault code is generated by the programming CPU card. This fault code is displayed if the temperature around the NTC sensor is below approx. -9 degrees C.

A low temperature means the resistance in the sensor is too high, above approx. 23.7 kohm. This can be because the machine has been standing outdoors, an open circuit in the sensor, a break in the cable to the sensor, etc.

The resistance should be as shown in the table below:

Approximate values of a fault free temperature sensor

T (°C) R (ohm)

19 6100

20 5850

21 5600

22 5350

23 5100

Fault code 05, NTC HIGH TEMP

This fault code is generated by the programming CPU card. This fault code is displayed if the temperature around the NTC sensor exceeds +98 de-grees C.

A high temperature means the resistance in the sensor is too low, lower than approx. 350 ohm. This can be caused by a short circuit in the sensor, break in the cable to the sensor, etc.

Fault code 06, WATER IN MACHINE

This fault code is generated by the programming CPU board. This fault code may appear only in the case of rapid advance to the end of the program. The fault code will appear if the level system has not indicated “empty drum” within a certain time (approx. 3 min). This time may vary depending on the size of the machine.

Action:

• Checkdrainfordirt.

• Blowthroughthelevelhoseandcheckthatitisnotblockedanddoesnot contain any water.

• Checkintheserviceprogramthatthelevelcontrolisworkingcorrectly.

• Addingtoomuchdetergent

27Troubleshooting

Fault code 07, DRUM OVERFILLED

This fault code is generated by the programming CPU board. The fault code arises if the drum has been filled with water above a predetermined level during an on-going wash program. It can be caused by a blocked level hose, drops of water in the level tube, defective filler valve, defective electronic filler control, etc.

Action:



• Checkusingtheserviceprogramthatallthewatervalvesareworkingcorrectly.

Fault code 08, NO HEATING

This fault code is generated by the programming CPU board. The fault code means that the temperature is rising too slowly when heating is active. The limit for this fault code is normally set to a water temperature increase of approx. 3°C per 10 minutes but can vary depending on the type of machine and the software.

The fault code can be caused by a defective heater element, a break in the power supply to the heater element, defective heater contactor, etc.

On machines built for washing mops, it can be caused by too low a level in the program stage. The lowest level for a mop program in the main wash with heating is 90 scale units.

28 Troubleshooting

Fault code 09, KLIXON

This fault code is generated by the programming CPU board. The fault code means that the temperature in the motor has been so high that the klixon breaker in the motor has been triggered. It can be caused by over-loading the motor due to an overloaded drum, low rpm for long periods, defective klixon breaker in motor, short in cable between motor and CPU board, etc.

Fault code 09, DRUM OVERFILLED (only in coin operated machines)

This fault code is generated by the programming CPU card. The fault code is caused by the mechanical level control in the machine, by safety reason a doubled level system. The fault code arises if the drum has been filled with water above a level that normaly should have generated fault code 07.

It can be caused by a blocked level hose, drops of water in the level tube, defective filler valve, defective electronic filler control, etc.

Action: see fault code 07.

Fault code 10, DRUM NOT DRAINED

This fault code is generated by the programming CPU card. The fault code arises if the water in the drum is not below a predetermined level when a drain period has been completed in the wash program. It can be caused by a blocked drain, blocked level hose, a water drop in the level hose, de-fective level control, restricted drain lines to the machine, too many machi-nes emptying simultaneously into drain pipes that are too narrow, etc.

Action:

• Firstcheckthedraininstallationandthatthewastewatercanflowfre-ely out from the machine without any restrictions.

• Checkthedrainvalveinthemachinewithregardtodirt.



29Troubleshooting

Fault code 11, UNB. ON AT PROG. START

This fault code is generated by the programming CPU board. The fault code means that the mechanical imbalance breaker is already active when the wash program starts. It can be caused by a defective imbalance brea-ker, mechanical problem making the imbalance breaker always active, short in the edge connection or cables, etc.

Fault code 12, PROGRAM FAILURE

This fault code is generated by the programming CPU board. This fault code means that one of the CPU board memories can be defective.

Action:

• Tryreloadingthesoftwareintothemachinememory.Ifthisdoesnothelp, the CPU board will have to be replaced.

Fault code 13, NO MOTOR COMM.

This fault code is generated by the programming CPU board. The fault code arises if the CPU board cannot communicate with motor control via the communication cable.

Actions:

• Checkthatthereispowerreachingthemotorcontrol.

• ThencheckthattheindicatorLEDonthemotorcontrolison.TheLEDcan be seen by looking down by the motor control edge connections.

• CheckalsothatthecommunicationcablebetweentheCPUboardandthe motor control is intact and not damaged. Measure also with a refe-rence instrument to see whether there is contact between all the leads in the communication cable.

Fault code 14, LEVEL ADJUST

This fault code is generated by the programming CPU board. The fault codearisesifthecircuitboard’sinternallevelsystemhasnotbeencalibra-ted by the manufacturer.

30 Troubleshooting

Fault code 15, EMERGENCY STOP

This fault code is generated by the programming CPU board. The fault code arises if the emergency stop switch has been activated on the mach-ine.

The cause can be inadvertent activation of the emergency stop, defective emergency stop switch, incorrect or shorted cable, etc.

Fault code 17, DOOR LOCK

This fault code is generated by the programming CPU card. The fault code arises if the door lock is locked at the start of the wash program, i.e. that the door is locked although the CPU board has not requested locking. This fault code will be shown if one try to start a program when the DLCU has given a fault code.

Fault code 18, START NOT ALLOWED

Themachine’sprogramunithasbeendisabledbyasuperiormonitoringsystem.

Actions

• Getintouchwiththesupplierofthemonitoringsystemforpossiblecauses of the monitoring system disabling operation of the wash machi-ne.

Fault code 19, MASTER COMM.

Communication with superior system has been broken. The cause can be a fault in the network connections, damaged cable, defective monitoring system, etc.

Action:

• Firstly,contactthesupplierofthemonitoringsystemforpossiblecau-ses of the monitoring system not communicating.

31Troubleshooting

Fault code 20, I/O MCU INTERLOCK

This fault code is generated by the programming CPU board. The program controller has read from the motor control or I/O board that the interlock is not active. The reason for interlock failure can be a problem with the hatch lock, damaged motor supply cables or the I/O board with interlock voltage etc. The most probable fault source is the I/O board.

Fault code 21, I/O COMMUNICATION

This fault code is generated by the programming CPU board. The pro-gram unit cannot communicate any longer with one or more I/O boards in the machine that it has communicated with before. The cause can be a problemwiththemachine’sinternalcommunicationcablesorthatoneormore I/O boards have lost their address.

Action:

• (Requirespassword)Checkthemachine’sinternalcommunicationcables. Readdress all the I/O boards in the system using the service program if the cables are not at fault.

Note. If only one I/O-card in mascine, press the service button on the I/O-card about 10 seconds or untill the LED goes out. Now I/O.card 1 will be addressed as No. 1.

Fault code 22, OIL

This fault code is generated by the programming CPU board. The fault code indicates low oil level in the oil reservoir for the oil lubrication. It can be caused by a lack of oil, defective sensor, shorted cable, etc.

Action:

• Fillwithoilfirst.Ifthisdoesnothelp,checksensorandcables.

32 Troubleshooting

Fault code 23, NO I/O ADDRESSED

The fault code means that there is no I/O board addressed in the system at all.

Action:

• (Requirespassword)ReaddresstheexistingI/Oboardfromtheservice

menu.

Fault code 24, CHECKSUM FROM DLCU

This fault code is generated by the programming CPU board. The program unit has detected a fault in the internal communication in the DLCU-pro-cessor.

Action:

• ReplacetheCPUboard.

Fault code 27, LEVEL OFFSET

This fault code is generated by the programming CPU board. The fault code arises if the level system indicates a level at the start of the wash program (when the drum should be empty) that exceeds what the program unit can compensate for automatically. This can be caused by blocked drain, blocked level hose, a drop of water in the level hose, leaking level system, defective level control, etc.

Action:

• Checkdrainfordirt.



33Troubleshooting

Fault code 28, CPU/DLCU LOW LEVELS

The DLCU contains a mechanical level monitor which ensures that there is no water in the machine when the lock opens. To ensure that the level monitor functions correctly, the mechanical level monitor is compared with a nominal value generated by the CPU, which is compared with the elec-tronic level check.

When the water level exceeds the nominal value, a check is made to ensure that the mechanical level monitor is switched on, and if so, a fault code is generated.

Reason:

• Thelevelcontrollercanbedamaged:

• Crosstalkinthelevelcontrollerelectricalsystem.

• Leakageinthelevelcontroller’sairhoses.

• Incorrectnominalvalue,possiblycausedbyafaultintheelectroniclevel controller.

Action:

• Checkthelevelcontrollerfunction.(Switch-onlevel=40mm,switch-offlevel=15mmWg)

• Checkthecablesandtheirconnections.Thevoltageacrossthelevelcontrollershouldbe0Vwhenthewaterlevelis<15mmWgand5Vwhen water level is > 40 mm Wg.

• Checkthatthelevelhosesarenotblocked.Blowcleanallthehosesinthe level system.

Fault code 31, HEAT SINK TOO HOT

This fault code is generated by the motor control. There is a temperature sensor (NTC) mounted on the motor control cooling flange next to the po-wer transistors in the output stage. If the temperature of the cooling flange gets too high (> 90°C) the fault code will be set to protect the transistors.

The cause of high cooling flange temperature can be e.g. a stiff drum in combination with intensive use and high ambient temperature. There may also be a fault in the motor (sticking bearings or short circuit in windings, which impairs the efficiency of the motor). There may also be a fault in the motor control temperature measuring circuits.

Actions:

• Makesurethedrumturnseasily.

• Checkthevalueonthefaultcodecounterforfaultcode31.

• Checkthelast8motorcontrolfaultcodes.

• Starta90°Cnormalprogramwithloadoncontinuousoperationandmeasure the temperature of the motor and motor control.

• Replacethedefectivepart.

34 Troubleshooting

Fault code 32, MOTOR TOO HOT

This fault code is generated by the motor control. Each time the motor is started from stationary, the motor control will first measure the resistance between two phases in the motor. The motor control processor governs the output transistors so that a determined DC current flows between two phases in the motor winding. The actuation of the transistors is a measure of the voltage applied to the winding and the resistance can be calcula-ted using the current and voltage values. The resistance can then be converted to a temperature since the winding resistance at 20°C and the temperature coefficient are known. If the average value of the four latest temperature readings is higher than the maximum motor temperature (e.g. 130°C), the ”Motor too hot” fault code will be activated.

The cause of high motor temperature can be a stiff drum, possibly in com-bination with intensive use and high ambient temperature. There may also be a fault in the motor (sticking bearings or short circuit in windings, which impairs the efficiency of the motor). There could also be a contact fault in the connectors between the motor control and the motor or a fault in the motor cable. A fault in motor control temperature measurement circuits can also occur.

Actions:

• Makesurethedrumturnseasily.

• Checkthevalueonthefaultcodecounterforfaultcode32.

• Checkthelast8motorcontrolfaultcodes.

• Measurethethreephasestothephaseresistorsonthemotorcontrolmotor connector (disconnect motor control and take the reading in the cable connector) to make sure they are the same.

• Starta90°Cnormalprogramwithloadoncontinuousoperationandmeasure the temperature of the motor and motor control.

• Replacethedefectivepart.

35Troubleshooting

Fault code 33, NO INTERLOCK

This fault code is generated by the motor control. The motor control must bepoweredwith230V/50Hzontheinterlockinputinordertodrivethemotor. This signal is confirmation that the door is closed and locked. Mo-tor control receives its commands to rotate the drum from the timer via a serial communication link between the motor control and timer. Since the timer also has access to the interlock signal, the timer must never send a run command to the motor control if the interlock signal is missing. If this does happen, the ”No interlock” fault code will be activated.

The cause of this fault code being activated can be e.g. a break in the cable leading the interlock signal to the motor control. There may also be afaultintheconnectorinthedoorlock,whichconnects230V/50Hztotheinterlock signal. A fault in the interlock circuits of the motor control can also set this fault code.

Actions:

• UseameasuringinstrumenttocheckthattheinterlocksignalcomesonX302:1-2 when the door lock is activated. Read also bit 1 in the second bye under ”Motor Status” in the service program (the bits are numbered from 0 to 7 where bit 0 is on the far right). If bit 1 in the second byte is 1 then the lock is open, while a 0 indicates that the lock is closed.

• Replacethedefectivepartwhenithasbeenlocated.

36 Troubleshooting

Fault code 35, MOTOR SHORT CIRCUIT

This fault code is generated by the motor control. The motor control reads the power consumption of the motor continuously. If the current for some reasongetstoohigh(=exceedsacertainlimit),themotorcontrolwillcutthecurrenttothemotor.Afterthemotorhasstopped(=tachometerindi-cates stationary motor), the motor control will attempt to restart it. If the motor control then detects high motor current again, the ”Short circuit motor” fault code will be activated. If on restarting after a first short circuit, the motor control rotates normally, a fault code will not be activated.

This fault code can be activated for a number of reasons:

• Shortcircuitinmotor

• Shortcircuitinternallyinmotorwinding(impairedefficiency,highercur-rent consumption)

• Shortcircuitinmotorcables

• Shortcircuitinconnectors

• Dropsofwatercausingshortcircuitsinthemotorconnector

• Shortcircuitinthemotorcontroloutputtransistors

• Badcontactintachosignal

• Badcontactininterlocksignal

Actions:

If the fault is a stable one, it is generally not difficult to locate the defective unit through resistance measurement and testing with the service program. Further information can be obtained by studying the contents of ”MCU FAULT LOGGER”. Study the following:

• SHORTCIRCUIT2(specifieshowmanytimesfaultcode35hasbeenactive)

• SHORTCIRCUIT1(specifieshowmanytimesthecurrentlimithasbeenexceeded. The difference between short circuit 1 and short circuit 2 indicates how many times there has been a short circuit 1 that has not been confirmed when restarting the motor).

• LASTFAULTCODEN/8(showsthe8latestfaultcodes)

• TACHOCUT-OUTLOWRPM(cangiveaclueincaseofintermittentfaults)

• TACHOCUT-OUTHIGHRPM(cangiveaclueincaseofintermittentfaults)

37Troubleshooting

Fault code 36, INTERLOCK HARDWARE

This fault code is generated by the motor control. The motor control must bepoweredwith230V/50Hzontheinterlockinputinordertodrivethemotor. The interlock circuits in the motor control have been split into two channels so that a component fault in motor control cannot give a false confirmation that the door is locked. These two channels are checked against each other. If this check gives an incorrect result, the ”INTERLOCK HARDWARE” fault code will be activated.

The reason for this fault code being activated can be attributed to a fault in the interlock circuits in motor control.

Action:

• Replacemotorcontrol.

Fault code 37, LOW DC VOLTAGE

This fault code is generated by the motor control unit. The motor control unit constantly measures the voltage over the mains input. If the voltage istoolow(=fallsbelowacertainlimit),themotorcontrolunitwillshutoffthecurrenttothemotor.Oncethemotorhasstopped(=thetachosensorindicates that the motor is stationary), the motor control unit checks to see whether the input voltage is still low. If it is, a fault code is activated: ”LOW DCVOLTAGE”.

The reason for this fault code being activated can be low mains voltage or thatthemachine’son/offswitchhasbeenoperatedinanunsuitableman-ner. Further information can be obtained by studying the contents of ”MCU FAULT LOGGER”:

• UNDERVOLTAGE2(specifieshowmanytimesfaultcode37hasbeenactive)

• UNDERVOLTAGE1(specifieshowmanytimesthevoltagehasdrop-ped below the limit. The difference between undervoltage 1 and under-voltage 2 indicates how many times there has been an undervoltage 1 without it being confirmed when the motor has stopped).


Undervoltages can be registered even during normal operation. Conse-quently, a small number of registrations need not mean that there is a fault in the motor control.

Measure:

• Checkthatthesupplyvoltageisstableandneverdropsbelownominalvoltage - 10%.

• Checkthatthefusesandcablesarenotfaulty.

• Checkthesupplyvoltageinthenetworkcablingandatthemotorcon-trol system in the machine.

38 Troubleshooting

Fault code 38, HIGH DC VOLTAGE

This fault code is generated by the motor control unit. The motor control unit constantly measures the voltage over the mains input. If the voltage istoohigh(=exceedsacertainlimit),themotorcontrolunitwillshutoffthecurrenttothemotor.Oncethemotorhasstopped(=thetachosensorindicates that the motor is stationary), the motor control unit checks to see whether the input voltage is still high. If it is, a fault code is activated: ”HIGHDCVOLTAGE”.

The reason for this fault code being activated can be high mains voltage (e.g. power surge). Further information can be obtained by studying the contents of ”FC FAULT LOGGER”:

• OVERVOLTAGE2(specifieshowmanytimesfaultcode38hasbeenactive)

• OVERVOLTAGE1(specifieshowmanytimesthevoltagelimithasbeenexceeded. The difference between overvoltage 1 and overvoltage 2 gives the number of times overvoltage 1 has occurred without it being confirmed when the motor has stopped).


Overvoltage registrations can also occur if there is a bad contact in the tacho signal. Check also the following registers:

• TACHOCUT-OUTLOWRPM(numberofshorttachointerruptionsduring wash rpm)

• TACHOCUT-OUTHIGHRPM(numberofshorttachointerruptionsduring extraction rpm)

Action:

• CheckthetachocablesiftherearemanyregistrationsintheTACHOCUT-OUT registers.

39Troubleshooting

Fault code 45, MOTOR NOT FOLLOW

This fault code is generated by the motor control. The motor control must always receive information on the rotation of the motor from the tacho sensor in order to rotate. If the tacho sensor is not working, the motor can rotate for max. 10 seconds during the starting process. After this period, the ”MOTOR NOT FOLLOWING” fault code will be activated.

Reasons for this code being activated can be:

• Breakinthecablesbetweenthetachosensorandthemotorcontrol

• Breakinconnectorsintachocables

• Breakinoneofthephasestothemotor(cablesorconnectors).Thisfault can be suspected if the motor does not rotate for 10 seconds (the motor will not start with only two phases).

•Faultintachogenerator

•Faultintachocircuitsinthemotorcontrol

Further information can be obtained by studying the contents of ”FC FAULT LOGGER”. Study the following:

• MOTORNOTFOLLOWING(specifieshowmanytimesfaultcode45hasoccurred)


• TACHOCUT-OUTLOWRPM(cangiveaclueincaseofintermittentfaults)

• TACHOCUT-OUTHIGHRPM(cangiveaclueincaseofintermittentfaults)

Action:

• Replacethedefectivepartwhentroubleshootingiscomplete.

Fault code 51, CHECKSUM FROM CPU

DLCU has detected a fault in the internal communication between DLCU and CPU. The DLCU processor will reset itself when the fault has disap-peared.

CPU reads the fault message when the program starts and finishes and generates a fault code, the fault message is ignored between these two occasions.

Reason:

Strong interference from surrounding equipment etc. can cause fault co-des.

Action:

Re-set the fault codes. If the fault codes can not be re-generated or if they return, rectify the adjacent equipment that causes the interference. If this does not help, try changing the CPU board, since the interference sensiti-vity of different CPU boards can vary to some extent.

40 Troubleshooting

Fault code 52, CHARGE CIRCUIT

DLCU contains an arming circuit that is charged when the door lock coil is to be activated. For safety reasons, this arming circuit must be discharged when the door lock coil is not to be activated.

If the arming circuit for operating the door lock is charged when it is not supposed to be, a fault message will be sent to the CPU processor. If the fault ceases, the message will not be sent to the CPU.


Cause:

• Theerrorcanhavebeencausedbyoverloadsand/ordefectivecompo-nents in the DLCU, or caused by defective components in the CPU.

Measure:

• Iftheerrorcannotbecorrected,replacetheCPUunit.

Fault code 53, CPU/DLCU HIGHLEVELS

The DLCU contains a mechanical level monitor which ensures that there is no water in the machine when the lock opens. To ensure that the level monitor functions correctly, the mechanical level monitor is compared with a nominal value generated by the CPU, which is compared with the elec-tronic level check.

When a program starts or terminates, a check is made to ensure that the mechanical level monitor is switched off, and if this is not the case, a fault code is generated.

Reason:

• Thelevelcontrollercanbedamaged:

• Opencircuitinthecablesforthelevelcontroller.

• Blockedairhosesinthelevelcontrollersystem.

Action:

• Checkthelevelcontrollerfunction.(Switch-onlevel=40mm,switch-offlevel=15mmWg)

• Checkthecablesandtheirconnections.Thevoltageacrossthelevelcontrollershouldbe0Vwhenthewaterlevelis<15mmWgand5Vwhen water level is > 40 mm Wg.

• Checkthatthelevelhosesarenotblocked.Blowcleanallthehosesinthe level system.

41Troubleshooting

Fault code 54, TACHO, NO SET SIGNAL

DLCU counts the tacho pulses from the motor in order to guarantee that the drum is stationary when the door is opened. To ensure that the signal from the tacho generator is working correctly, DLCU compares the tacho signal to a default value from the CPU processor, which is due to the CPU having activated the motor. The tacho signal should always correspond to the default value and if the tacho signal is present without the default value, a fault message will be generated to CPU.

The fault message is filtered in such a way that the drum must rotate and stop twice without the ”should rotate” signal being present before a fault message is sent to CPU.

The DLCU processor will reset itself when the fault has disappeared.

CPU reads the fault message when the program finishes and generates a fault code, the fault message is ignored between these two occasions.

Reason:

The fault can be caused by cross talk in circuits in the CPU, or caused by damaged components in the CPU.

Action:

If the fault returns after a reset, change the CPU.

42 Troubleshooting

Fault code 56, SET SPEED DOOR OPEN

DLCU counts the tacho pulses from the motor in order to guarantee that the drum is stationary when the door is opened. To ensure that the signal from the tacho generator is working correctly, DLCU compares the tacho signal to a default value from the CPU processor, which is due to the CPU having activated the motor.

If the default value is on when the door lock is unlocked, a fault message will be sent to CPU.



Reason:

The fault can be caused by cross talk in circuits in the CPU, or caused by damaged components in the CPU.

Action:

If the fault returns after a reset, change the CPU.

Fault code 58, SET SIGNAL NO TACHO

DLCU counts the tacho pulses from the motor in order to guarantee that the drum is stationary when the door is opened. To ensure that the signal from the tacho generator is working correctly, DLCU compares the tacho signal to a default value from the CPU processor, which is due to the CPU having activated the motor. The tacho signal should always correspond to the default value and if the tacho signal is not present when the default value is present, a fault message will be generated to CPU.

The fault message is filtered in such a way that the default value should have been on for 2 seconds; if this is the case, a check is made that the pulses from the tacho sensor are present when the default value ceases.



Reason:

• Thefaultcanbecausedbybreaksinthecircuitsforthetachosensor,or caused by a fault in the magnet in the tacho sensor.

• Collateraldamageduetoafaultinthemotorsystem.

Action:

• Ifthereisnofaultinthetachosensororthemotorsystem,andthefaultreturns after a reset, change the CPU.

43Troubleshooting

Fault code 60, ACTUATOR CIRCUIT

The DLCU processor controls the door lock actuator coil. The DLCU pro-cessor checks continuously that the coil is engaged. DLCU can detect a break in the circuit (>50 kohm) (DLCU cannot detect a short in the circuit). If there is a break in the actuator circuit, CPU will be notified; the fault message will disappear if the fault ceases.


Reason:

•Thefaultcanbecausedbyabreakinthecablesbetweenthehatchlockand the CPU, or caused by a fault in the hatch lock solenoid.

•FaultorbreakintheCPUcircuits.

Action:

•Ifthefaultreturnsafterareset,andisnotcausedbyafaultinthehatchlock or the cables for the hatch lock, change the CPU.

Unbalance detection

When the drum in a drain sequence starts its acceleration from wash rpm to distribution rpm, the extreme unbalance measurement will start once about 90% of the distribution rpm has been attained. Subsequently, during the entire remaining super unbalance measurement, the distribution time and during the entire subsequent extraction time, the program unit will detect whether there is any extreme unbalance.

In case of extreme unbalance that can arise if e.g. a spring strut is defec-tive or when washing in sacks, the acceleration will be stopped to wait for the drum to stop. If extreme unbalance arises during:

a. distribution or during super unbalance measurement, the drain sequen-ce will restart from the beginning. The number of restart attempts can be changed in the system data but is usually set to 5. The value can also be changed via configuration 2.

b. extraction, the program will stop and move to the wash sequence after extraction.

I/O modulesGeneral

Washing machines may be equipped with either one or two I/O modules:

• I/Omodule1controlsinternalmachinefunctionsandisalwaysinstal-led in the machine prior to delivery. It controls outputs to water valves, waste discharge and heating.

• I/Omodule2isinstalledasanoptionalextra,controllingtheexternalfunctions of the machine, i.e. inputs from payment and booking sys-tems and outputs to detergent pumps.

The functionality of I/O module inputs and outputs is dependant on the parametersoftwaredownloadedtothemachine’sprogramdevice.Thefunction options for the I/O modules are indicated by a letter in the pro-gram designation for each module and, together with the article number of the parameter software, shown in the ARTICLE NUMBER menu of the service program as per the following example:

Program designation

Article number shown in the service program

If the second letter (I/O module 2) appears in lower case, it means that the machine is not fitted with I/O module 2 but the downloaded parameter software is I/O module 2 enabled.

Program designation

Article number shown in the service program

If the machine subsequently fitted with I/O module 2, the module will ac-quire the function option as specified by the second letter once the new I/O module has been addressed.

Door and door lockDescription

General

The door locks consists of the following:

• Door lock, which contains

- An actuator that locks the door lock and also has two built-in micro switches, S4a and S4b. The actuator is bi-stable, i.e., it has two stable positions: locked door and unlocked door. The actuator must receive a pulse to lock and unlock the door lock. S4a and S4b are both closed when the door is locked.

- A micro switch S3 that is closed when the door is closed.

- An emergency opening button that can be used to open the door lock in an emer-gency.

Function

The door lock locks the door

When the door is closed (closed door lock switch S3), the programme unit mayrequestdoorlockingbyapplyingavoltageof200-240Vonthedoorlock controller A31 input X92.

The following check is made by the A31 card prior to locking of the door:

• No water in drum-input"level"fromlevelguardB2isclosed=0V

• Drum not turning - pulse frequency on input "Tacho" from rotation sensor B3 less than 0.4 Hz.

When the above conditions are met, the card A1 outputs a closing pulse on output D0 to the door lock actuator/coil, which then locks the door. The micro switches S4a and S4b in the actuator/door lock are closed when the door is locked. These micro switches feed voltage to:

• The output relays on the programme unit card. The relays control the machine’sdrainandwatervalvesaswellasheaterswitch-on.

• Interlock signal for motor control (input X302) that releases the motor start prevention state.

Programme operation is now possible.

When the above conditions are met, the door lock controller outputs an opening pulse on output D0 to the door lock actuator/coil, which then unlocks the door. Micro switches S4a and S4b now interrupt the actuator/door lock and the I/O card 1 relays lose all voltage to prevent the motor from starting (interlock signal on motor controller input X302). The drain and water valves of the machine are now disabled and the heater and mo-tor cannot be switched on.

Description

Motor

The motor is fitted in a bridge carrier under the outer drum. It drives the washing drum using a drive belt.

The motor is frequency-regulated and is con-trolled by a microcomputer control. The vari-ous speeds for normal operation, distribution speeds and extraction as well as acceleration/retardation can be controlled with a high de-gree of precision.

The motor winding is protected against over-load due to the fact that the motor control unit monitors the winding resistance of the motor.

The motor is connected directly to the motor controller via a cable with quick connectors.

Motor control

The motor control unit is microcomputer control-led and is situated under the top cover of the machine, right above the outer drum.

The unit consists of a PCB (mother board) fitted on a heat sink that does double-duty as part of the housing.

The cable harness is directly connected to the PCB, voltage supply input and the voltage supply to the motor using connectors; the other cables are connected with flat connectors to the PCB.

A detailed description of input and output cables is presented in the section “Function”.

Depending on the machine size, this unit comes in four different versions. The units have different sizes in order to be able to control motors of dif-ferent sizes. Larger machines also have ventila-tion fans, however the function and connections are identical.

The motor control communicates with the programme unit via a serial two-way interface. With the help of the motor control, the programme unit can control not only the instantaneous motor rpm, but also with high precision the acceleration and retardation of the motor in order to reach the target rpm. The motor control continuously replies with information to the pro-gramme unit PCB regarding the current operating state and sends reports if an error occurs.

The motor control is also able to deliver the various instantaneous and output values during constant speed, acceleration and retardation. These values are used to calculate the weight of the loaded laundry and to detect any load imba-lances. A separate imbalance switch can also be connected to the motor control.

The safety system of the machine includes double detection of the door lock. Both the programme unit and motor control use different switches to detect proper door locking. The mo-tor cannot start unless both switches verify the door is locked.

Drain valveDescription

The drain valve is situated on a flange at the bot-tom of the outer drum and can be accessed from the front after removing the front cover. The drain valve consists of the following principal parts:

• Lowerpartwithrubberdiaphragm.

• Pistonandcylinder.

• Pressureplateandrecoilsprings.

• Rubberdiaphragmwithdrainconnection.

• Upperpartwithconnectionforouterdrum.

Drain valve

Drain valve

Drain valve

H – model

M och N – model

106

Function

The drain valve uses the water pressure in the cold-water inlet to close the valve. A feed hose is connected between the water inlet and the control valve.

When the control valve operates (drain valve should be closed), the control valve opens the water pressure onto the feed hose, which is con-nected to the lower part of the drain valve. When the lower part is filled with water, the lower part diaphragm pushes up the piston. The piston lifts the pressure plate against the drain valve rubber diaphragm, which in turn forms a seal against the outer drum, effectively closing the valve.

When the drain valve should be opened, the control valve changes position to allow the water pressure to the lower part of the drain valve to close, instead opening the return hose to the drain. The pressure plate recoil springs pull the pressure plate back, upon which the piston is pressed back into the cylinder. The water from the lower part is fed through the feed hose and the control valve to the drain.

Detergent compartmentDescription

The detergent compartment of the machine is designed for use with powder and liquid deter-gent. The compartment is divided into four sub-compartments as follows:

• Compartment1-Forprewashwithpowderor liquid detergent.

• Compartment2-Formainwashwithdeter-gent powder.

• Compartment3-Rinse.

• Compartment4-Mainwashwithliquidde-tergent or, bleaching-agent.

The connections for incoming water are situated on the rear side of the compartment. Compart-ments 3 and 4 each have one connector, while compartments 1 and 2 each have two con-nectors, one for cold water, the other for warm water.

The detergent is routed from the bottom of the compartment to the outer drum through the combo module immediately behind the compart-ment.

To safeguard against overfilling, e.g., due to a blocked hose on its way to the drum, the combo module features an overflow drain directly con-nected to the drain of the machine.

Function

Electric heating with fusible cut-out on element

The three heating elements in the machine are connected to separate phases and are switched on and off using one or two heating contactorrs, K21 och K22 (two contactors are used for higher heating power). The heating contactors are con-trolled by the programme unit A1, output (X36:7).

The programme unit receives information on the water temperature in the machine through an analogue signal from the temperature sensor situated in the outer drum. The programme unit controls the heating contactors to achieve the set water temperature for the current washing programme.

When there is no water in the drum, the pro-gramme unit prevents switch-on of the heating elements. If an error would nevertheless cause the elements to switch on, a slow-blow fuse trig-gers to switch them off again. Then the heating elements has to be changed.

Function (machines built for mop washing)

Electric heating without fusible cut-out on element

The three heating elements in the machine are connected to separate phases and switched on and off using two serial heating contactors. Hea-ting contactor K21 is controlled by programme unit A1, output (x36:7). Heating contactor K22 is regulated by a standalone mechanical level con-trol. In order for both contactors to be activated, the level in the machine must have been appro-ved by both the level control in programme unit A1 and the mechanical level control.

The water level in the machine must be 90 scale units or more in order for the mechanical level control to be activated.

The programme unit receives information on the water temperature in the machine through an analogue signal from the temperature sensor situated in the outer drum. The programme unit controls the heating contactors to achieve the set water temperature for the current washing programme.

The mechanical level control prevents the ele-ment from activating if the programme unit or-ders heat despite the fact that there is no water in the drum.

- Let the door remain open and try starting the machine. The machine should not start.

- Close the door, start the machine and try opening the door. It should not be possible to open the door until the drum has stopped turning.

- Check that the door does not leak.

- Clean the door seal, removing any detergent and fluff.

• Checkthatthedrainvalvedoesnotleakduringthewashcycle.

• Cleanoutanydetergentremaininginthedetergentcompartment.Rapidadvance through a program and let the water rinse the compartment:

Every third month

May only be carried out by authorized personnel.

• Checkthatthedoordoesnotleak.

• Checkthedrainvalveandremoveanyfluff.

• Inspecttheinteriorofthemachine(duringanactualwashcycletoen-sure that no leaks are noticed) by:

- Turning of the main power switch of the machine.

- Remove the top cover and the protective front and rear plates.

Preventive maintenance

120

- Verifythatallinternalhosesdonotleak.

- Inspect the drive belt. Adjust the tension or replace if necessary.

- Check that water does not leak onto the floor.

- If the heating time is unusually long, check the heating elements. If the water is very hard, check whether there are lime deposits on the heating elements. Decalcify the elements if necessary. Adapt the amountofdelimingagenttothemanufacturer’sguidelines.

- Never switch on the heating elements when there is no water in the machine. This will cause the slow-blow fuse to trigger.

- Inspect the shock absorbers and coil springs. (Only EX- and H-model).
